　　Steel freezerThe principle of copper sleeve cold treatment box and industrial cold treatment box

The so-called cryogenic treatment is to continue the cooling process of quenched metal materials to a temperature far below room temperature, promoting the further transformation of residual austenite existing after conventional heat treatment into martensite that can harden and strengthen the steel, thereby improving the properties of the metal material. Deep cryogenic treatment can significantly improve the wear resistance, toughness, and dimensional stability of metal tools, doubling the service life of workpieces; It has been applied abroad to modify cutting tools, measuring tools, molds, and precision parts such as oil nozzles for oil pumps, turbine shafts for engines, rollers, valves, gears, springs, and other workpieces.
